Mapping of the maize genome, beyond the framework and rough placement level, is more complex than may have been anticipated. Complexity can be attributed to at least the following factors: (1) failure to discriminate order, arising from mapping large numbers of markers on small populations; (2) limitations among suitable techniques, due to extraordinarily high levels of polymorphism and frequent but inconstant duplication; (3) limited applicability of large-fragment techniques, due to relative size of fragments vs. density of markers; and (4) limitations in utilities for conjoint analysis and representation of mapping data in graphical form. Current status of some advancing mapping projects, potential advances in technologies, and some developing utilities for comparative and selective map presentation will be shared and discussed in this workshop.
